The front panel groups Power, Reset, USB 3.0, two USB 2.0 ports and HD audio in a single clean line for convenient access. Constructed from 0.5 mm SPCC steel, the chassis is built for durability while maintaining a simple design. Internal drive bays and layout options allow customization of HDD and SSD placement to suit different storage needs.
